Overview Have you ever had that odd feeling that we're all living in a simulation? If you have, you are not alone. Many people have thought about this, resulting not just in amazing sci-fi entertainment content but also in the simulation theory which is constantly being backed up by more people. Simulations need to be populated by digital characters to give some sense of realism. However, defining exactly what makes these characters realistic is very difficult since it can be very subjective. Nevertheless, it can be broadly divided into two main categories: how realistic their visual representation is (rendering and animations) and how realistic their behavior is. That last category is the area which I’m more interested in, and what I’m currently researching as part of my master’s in com…  ( 9 min )

mongoose-reactions is a lightweight, TypeScript-first Mongoose plugin that adds Laravel-like polymorphic reactions (likes, loves, laughs, custom strings) to any model. This post shows why you’ll want it in your stack, how it works, quickstart examples, scaling tips, and how you can help the project grow (⭐ GitHub!).

The Rest Day That Wasn't Yesterday was scheduled as a rest day. My brain disagreed. Today was supposed to compensate, but by nightfall, I remembered exactly why I work—and it's not what you'd expect. Here's the uncomfortable truth: I don't work because I'm motivated. I work because when I don't, my mind spirals into random thoughts that drive me insane. I start craving human connection like I'm the protagonist in some friendship-power movie. Spoiler alert: Life isn't a movie, and coding has become my mental survival strategy.

Introduction IAM user access keys are the normal way to access AWS from an external source. Generally this is the method to use for machine/code access to your AWS estate. This is ok, but come with some issues: Long lived credentials expand the window of opportunity for an attacker to exploit the access key. Rotating secrets can be hard to manage; synchronising credentials rotating with third parties can be complex. It just doesn't scale, anything over a handful of access keys becomes hard to manage. The AWS preferred solution is to use AWS IAM Roles Anywhere for workloads outside of AWS. Short term rotating credentials Uses industry standard X.509 certificates Reduces management complexity Although a bit more complex to set up, AWS IAM Roles Anywhere is a much more elegant, scalable so…  ( 9 min )

When we perform a network scan, there are a few terms that often pop up and confuse beginners. One of them is the idea of channels and channel numbers. If you have ever seen a scan output that shows something like Channel 6 or Channel 11, you might wonder what that really means. Think of WiFi like a busy road. Many cars are moving in different lanes. If all cars tried to squeeze into the same lane, it would become messy and slow. WiFi channels work in a similar way. A channel is simply a small slice of the overall frequency band that WiFi uses. Instead of all devices communicating on the exact same frequency, the band is divided into multiple channels. Each channel is like a lane on that road, letting different devices talk without colliding too much. For example: In the 2.4 GHz band, ther…  ( 7 min )

Two weeks after launching GitNarrative with GitHub-only support, user feedback was clear: developers use multiple Git platforms. So I implemented OAuth for GitLab, Azure DevOps, and Bitbucket.

In a world where political systems collapse, alliances wobble, and everything seems to be on fire, one would at least hope the developer tools might offer a shred of stability. They don’t. I’ve worked with many ecosystems in my developer life. The one that has devoured the most of my sanity? Node. The idea is decent, no complaints there – but the sheer amount of time I’ve sacrificed just to get a dev stack breathing borders on ritual self-harm. Dependencies that loathe each other, transitive nightmares, versions that refuse to coexist – the chaos is biblical. Running npm install feels less like software engineering and more like rolling dice in front of an indifferent god of dependencies. Sometimes it works. Most of the time: head → desk. And then there’s Python. Honestly, it’s worse. Setting up environments isn’t development, it’s a horror show. Each setup feels like a new boss battle in a game nobody wanted to play. Pipenv, virtualenv, Poetry – all cheerful names, all equal pain. These days I mostly write Go. And frankly, I’m not going back. No virtualenvs, no Gradle, no cathedral of node_modules. Just go build, and it runs. Sure, Go has its quirks – private repos that act like they’ve never met you, or go mod tidy deciding to improvise like a drunken jazz band. But that’s all manageable. Nothing requiring daily therapy. I like Go. The language. The ecosystem. The peace.  ( 6 min )

Intro One-to-Many, or parent-child relationships are a common occurrence in application development. Off the cuff, we can think of numerous instances of this, like actual parents and their children indeed, a sports team with its players, etc. A natural solution to store this is to use a relational database and employ foreign key constraints to enforce data integrity. This post features the following use-case - loading the list of parents, and all their corresponding children (in one go). We'll look at how to do it efficiently when using Spring Data JPA and Postgres. We'll start with the slowest approach (hello, N+1!) and show how to make it faster through successive refinements. The code is available in this repo. Let's use a familiar scenario: authors and their books. Classic one-to-ma…  ( 11 min )

There comes a time in every developer’s journey when the code stops being a bunch of instructions and starts feeling… alive. The Phases of My Relationship with Code Infatuation "Hello World" worked. Confidence skyrocketed. Thought I was basically the next Linus Torvalds. Conflict The compiler: "Expected ‘;’ before ‘}’." Me: "I expected inner peace, but here we are." Counseling (aka Stack Overflow) Every answer feels like therapy. Except when the accepted solution is from 2009 and doesn’t compile anymore. Acceptance Bugs are not enemies; they’re misunderstood plot twists. Every error is just my code trying to tell me a story. The Twist Here’s the funny part: the more time I spend fixing bugs, the more I realize coding isn’t just about talking to machines. It’s about learning to listen. That TypeError? It’s just code saying: That Segmentation Fault? Takeaway Programming isn’t just building apps. It’s a weird, dramatic relationship between us and the logic we create. Some days, code loves us. Some days, it breaks our heart. Question for you: If your code could talk back, what’s the sassiest thing it would say?  ( 6 min )

Hello, I'm Shrijith Venkatramana. I’m building LiveReview, a private AI code review tool that runs on your LLM key (OpenAI, Gemini, etc.) with highly competitive pricing -- built for small teams. Do check it out and give it a try! Computers were never just about wires and chips. They've always been built for suiting human imagination - or more practically -- a workload. Or in reverse - the rule is: the workload defines the hardware. For half a century, workloads looked like this: operating systems making decisions, compilers checking conditions, databases searching records. All of them boiled down to logic -- if this, then that; otherwise, do something else. The machine for the job was the CPU: fast, flexible, and great at juggling complex, branching tasks. But AI has upended this. When yo…  ( 9 min )

Let's look into The Birth of Questions 🔮❓ So I'm currently reading the book called Sophie's World 📖, a beginner entry-level book for philosophy. And if you want to start reading and learning about philosophy, this is something you should start with. Well, at the staring of book there were questions. First one was: Who are you? 🪞 Which led me to think for quite a few days - knowing who I am actually, apart from these fancy job titles 👔 and self-proclaimed mysterious terms defining my nature, which I assumed or my perception of what others think of me.

A neural network is an information-processing model inspired by the human brain. Just like our nervous system is made up of interconnected neurons, a neural network consists of interconnected processing units (called nodes or artificial neurons). The key strength of neural networks lies in their parallel processing ability. Unlike traditional linear models, they can capture complex, non-linear relationships within data. This makes them highly effective for tasks such as pattern recognition, prediction, and classification in large or unstructured datasets. However, despite their power, neural networks are often called a “black box.” Users can clearly see the inputs and outputs, but the decision-making process inside is not always easy to interpret.

The AI dropped the ball on the cover art but I need to get some sleep. This whole circus kicked off months ago when I was still shackled to Windows 11. At first, I thought I could just mess around with some local LLMs using tools like Ollama and LM Studio. My Frankenstein laptop—an overclocked, duct-taped monstrosity that should’ve been retired years ago—was somehow pulling it off. But here’s the thing: no matter how much bloatware you purge, no matter how many “services” you assassinate with Task Manager, Windows still eats half your bloody resources at idle. GPU humming at 50% like it’s siphoning off GPU cycles to train Skynet or crypto mining Dogecoin on my dime. Paranoid? Maybe. Wrong? Probably not. So yeah, I switched teams.

__ But beneath that friendly interface lies a reality that most people don’t see: LLMs can be tricked. And not in a small way. With the right words, someone can bypass guardrails, manipulate outputs, or even convince an AI to “forget” its boundaries. These tricks are called adversarial attacks—and if AI is going to shape our future, we need to understand them. What Exactly Are Adversarial Attacks? Let’s simplify. Imagine you’re talking to a super-helpful friend who just can’t say no. They’ve been told not to reveal certain things—like how to hotwire a car—but if you rephrase your request cleverly enough, they might slip up. That’s basically how adversarial attacks work. Attackers don’t break into the AI’s system like hackers in movies. Instead, they manipulate language—the very thing LLMs …  ( 9 min )

In December 2015, a group of Silicon Valley luminaries announced their intention to save humanity from artificial intelligence by giving it away for free. OpenAI's founding charter was unambiguous: develop artificial general intelligence that “benefits all of humanity” rather than “the private gain of any person.” Fast-forward to 2025, and that noble nonprofit has become the crown jewel in Microsoft's $14 billion AI empire, its safety teams dissolved, its original co-founder mounting a hostile takeover bid, and its leadership desperately trying to transform into a conventional for-profit corporation.

If you’re running local AI tools like Ollama, Jan, LM Studio or llama.cpp, one of the first things you’ll want to know is whether your GPU is up to the task. VRAM size, compute capability, and driver support all play a big role in whether models will run smoothly (or crash out of memory). A neat shortcut: if you have Node.js installed, you can run: npx —-yes node-llama-cpp inspect gpu Even though this command comes from node-llama-cpp, the output is universally useful. It quickly reports your OS, GPU, CPU, RAM, and driver metrics— that apply no matter which local AI framework you’re using.

But what exactly is Linux, and why do so many developers, tech companies, and even governments use it? Don’t worry — you don’t need to be a “computer wizard” to understand Linux. In this article, we’ll break it down in simple terms, step by step. At its core, Linux is an operating system (OS) — just like Windows on most PCs or macOS on Apple computers. 👉 An operating system is the bridge between your computer’s hardware (CPU, RAM, storage) and the applications you use (like browsers, games, or text editors). Without an OS, your com…  ( 8 min )

In Next.js, securing sensitive data and preventing the exposure of API endpoints is critical for building secure web applications. When fetching data, the approach you choose direct or indirect determines whether API endpoints are visible in the browser's network tab. This article explores how to hide API endpoints in Next.js, using two Proof of Concept (POCs) examples to compare direct and indirect data fetching. We'll demonstrate how direct fetching keeps endpoints hidden and provide best practices for securing your Next.js app, based on a project using Next.js 15.5.0, React 19.1.0, and Supabase. The examples in this article are based on a Next.js project with the following setup, Next.js (v 15.5.0) React (v 19.0.1) Supabase Directory Structure This setup uses a Supabase table named …  ( 8 min )

Hey there! Welcome to my journey of learning LangChain with AWS Bedrock. I'm documenting everything as I go, so you can learn alongside me. Today was my first day diving into this fascinating world of AI models, and honestly, it felt like having a conversation with the future. Quick Setup Note: I'm using AWS SageMaker Studio notebooks for this entire series - it comes with all AWS permissions pre-configured and makes the learning process super smooth. Just create a notebook and you're ready to go! LangChain is a Python framework that makes working with Large Language Models (LLMs) incredibly simple. Instead of writing complex API calls and handling raw JSON responses, LangChain provides a clean, intuitive interface. Why LangChain? Simplicity: One line of code instead of 20+ lines of API ha…  ( 8 min )

A Day in the Life of My Laziness Introduction I woke up in the morning, said my prayers, and then — instead of jumping into action I went straight back to sleep. Ten minutes of praying turned into thirty minutes of snoozing. When I finally got up again, I brushed my teeth half-awake, grabbed a quick breakfast, and dragged myself to work. At Work: The Art of Doing Nothing Work is quiet when I don’t have tasks, so I escape into YouTube. I never plan what to watch; I just click on whatever looks interesting. One video leads to another, and suddenly I’m watching something random that I didn’t even know existed. Coffee is my other weakness. One cup is never enough — the moment I finish, I crave another. It’s like my energy fuel, but instead of making me productive, it just he…  ( 6 min )

When people first step into the software world, it’s easy to confuse DevOps and Testing (QA). Both roles care about ensuring software runs smoothly, both are involved in deployment and release cycles, and both deal with “quality.” But in reality, they serve different purposes and complement each other in the software delivery pipeline. Let’s break it down. 🔹DevOps DevOps = Development + Operations Main tasks of DevOps: CI/CD (Continuous Integration / Continuous Deployment): ensure code from dev to production is fast, safe, and error-free. Automation: write scripts to automatically build, test, and deploy. Monitoring & Logging: monitor the system (CPU, memory, uptime, logs, alerts). Infrastructure as Code: use Docker, Kubernetes, Terraform to manage servers and environments. 👉 In short: D…  ( 6 min )

I like tools that stay on disk. I like Markdown that opens in any editor. Obsidian does both. The catch is sync. The official option is paid. I wanted control and a zero bill. Git and GitHub gave me both. The setup takes a few minutes. After that, it feels like magic you can explain. A private GitHub repository to hold your vault. Git on your desktop. Obsidian with the Obsidian Git plugin. On iPhone or iPad, iSH as a tiny Linux shell that can run Git. That is the whole cast. Open GitHub. Create a new repository. Name it something you will not hate later. Make it private. This is your vault’s remote. This is where history lives. Install Git if you do not have it. On Windows, grab Git for Windows. On macOS, use the Git installer or Homebrew. On Linux, use your package manager. Then conf…  ( 8 min )

I like tools that give me control. I like seeing the logs roll in my own terminal. I like knowing where the database file lives. n8n fits that mood. It connects your apps, moves your data, and runs on your own machine. When something breaks, you can still touch the files, read the config, and fix it. That is the point of a local install. There are two roads. Docker, where you get a neat, sealed box that behaves the same on every machine. Or Node and npm, where you install n8n like any other CLI and own the runtime. You can switch between them later, but it helps to pick the one that matches how you work today. First, a few truths. The editor listens on port 5678 by default. If something else is already there, you will hit a connection error. You can change n8n’s port with an environment va…  ( 10 min )

Why Your AI Journey Needs a System, Not Just Tools Jaideep Parashar ・ Aug 24 #ai #webdev #beginners #discuss  ( 6 min )

Most people start their AI journey by asking: “Which tool should I use?” And that’s exactly why they burn out. Because tools change. Systems don’t. Here’s why (and how) to shift your focus from tools → systems. Tools Are Temporary Today it’s ChatGPT, Claude, and Gemini. Tomorrow, new names will dominate. If your entire workflow depends on a single tool, you’ll have to start from scratch when the next one comes. Tools = tactics. Systems = strategy. What an AI System Looks Like A system is a repeatable workflow that works across tools. For example: Input: Gather raw info (emails, notes, data) Process: Use AI to organise, clean, and summarise Output: Turn into content, insights, or actions Review: Evaluate quality and adjust prompts This framework stays valid whether you use ChatGPT, Perplex…  ( 7 min )

Madhu Sudhan Subedi Tech Weekly Slot Machine Coding: Lessons from Building with AI Agents For two months, Sentry’s MCP team let AI agents write production code for a real cloud service. The outcome was mixed: agents are fast at scaffolding and boilerplate, but results can feel like a slot machine—sometimes a win, often follow-up refactoring, debugging, and cleanup. Detailed docs and explicit prompts helped, because LLMs struggle with recall and context without clear guidance.

Just a few days ago, while I was researching and writing Part One of “ARLIZ,” I saw and felt things I’m still digesting — so I decided to put this experience and these feelings down here, plain and simple, no fuss. First of all, one simple but deep thing showed itself in my notes: a lot of people really don’t understand what “you should give help to receive help” means. I’ve helped a lot on this path, taught things, pointed the way, but I often saw people expecting everything to be handed to them from the start; or when you help, it’s as if that help earned you a medal. My experience is that you don’t need everyone cheering you on for the smallest things. Most of the time you’re just a piece of the puzzle — a very small piece that, in some people’s eyes, might seem “useless” or “crappy” an…  ( 8 min )

Large Language Models (LLMs) have taken the world by storm, showcasing remarkable capabilities from generating creative content to answering complex questions. With this surge in LLM adoption comes the rise of "prompt engineering"; the art and science of crafting effective prompts to elicit desired outputs. But as data engineers, accustomed to the rigour of data pipelines and ETL processes, we might ask: Is prompt engineering truly a critical skill, or is it just the current wave of hype? The Core of Prompt Engineering: Clarity and Specificity: Vague prompts often lead to generic or irrelevant responses. Clearly defining the desired output format, constraints, and context is crucial. For example, instead of "Summarize this data," a better prompt would be, "Summarize the key trends in websi…  ( 7 min )

When you're building or testing an application that depends on other services—like APIs, databases, or third-party systems—you often hit a roadblock when those services are unavailable, slow, or incomplete. This is where service virtualization comes in. It helps you simulate those services so you can test and develop without being blocked. Before comparing tools, it helps to understand the different types of service virtualization. Not all tools focus on the same thing, and depending on your use case, one type may be more relevant than the others. 1. Database Virtualization This refers to mocking or simulating databases at the binary protocol level. Tools in this category simulate how databases like MySQL or PostgreSQL respond. But in practice, this kind of virtualization is rarely needed.…  ( 8 min )

If you are connected to a local network, whether at home, in a cafe, or at work, your devices need a way to talk to each other. One of the behind the scenes protocols that makes this possible is ARP, short for Address Resolution Protocol. ARP’s job is simple. It maps an IP address (like 192.168.1.5) to a physical MAC address (like a1:b2:c3:d4:e5:f6). Think of IP addresses as names and MAC addresses as phone numbers. ARP is the phonebook that helps one device find another on the local network. This is usually harmless, but the problem is that ARP was designed at a time when security was not a top concern. It trusts anyone who says “I am this IP address, and here is my MAC address.” Attackers can take advantage of this trust and that is where ARP Spoofing comes into the picture. ARP Spoofin…  ( 7 min )

What if the AI systems we build could take an active role in their own evolution? This is the question that drove my latest experiment. Many of you are familiar with my from-scratch neural network library, slmnet. After porting it from the browser to Node.js, I set myself a challenge: to stay within a pure JavaScript and Node.js environment. No Python wrappers, no C++ bindings. This constraint was intentional—it forced a deeper understanding and ensured that every part of the system was transparent and malleable. This foundation allowed me to explore a fascinating, advanced AI concept: creating a system that could learn to optimize itself. I architected a high-level supervisor, the Meta-Controller, designed to guide an AI agent (powered by slmnet itself) through a cycle of self-improvement…  ( 6 min )

Introduction The rise of AI tools has changed the way developers work. Two of the most talked-about tools are GitHub Copilot and ChatGPT. Both are built with AI, both help developers write better code — but they serve different purposes. So, should you use GitHub Copilot, ChatGPT, or both? In this article, we’ll break down the differences so you can make the right choice for your workflow. GitHub Copilot is an AI-powered coding assistant that integrates directly into your IDE (like VS Code, JetBrains, or Visual Studio). It provides context-aware code completions, function generation, and even test case suggestions as you type. Think of it as an “AI pair programmer” that works alongside you in real-time. ChatGPT is an AI chatbot built by OpenAI that can generate human-like text ba…  ( 6 min )

faketube.app In the previous episodes, we created a solid frontend foundation for our project - application shell and home page with a responsive UI and infinite scrolling.

Starting with a traditional approach with a REST API and SQL database, we will later move to a modern approach with a GraphQL based API and NoSQL database.

The latest MIT study reveals the harsh truth about AI in business A Fortune 500 company recently spent $2 million on an "AI agent" to handle customer service emails. After six months, the system still forwards every third message to humans because it can't determine if "I want to cancel my subscription" means someone actually wants to cancel their subscription. This corporate AI failure isn't an isolated incident. It's become the industry standard. A bombshell MIT study just revealed that 95% of generative AI pilots at companies are failing (MIT NANDA Initiative, "The GenAI Divide: State of AI in Business 2025", August 2025). Not struggling.

Introduction to Git Hooks Git is more than just a version control system. It also provides automation to improve developer productivity. One of these features is Git Hooks. Git Hooks are scripts that Git automatically executes before or after specific events, such as commiting code, pushing to a remote repository or merging branches. They allow developers to automate tasks seamlessly within the Git workflow. In simpler words, Git Hooks act like "triggered scripts" that run at different stages of Git's lifecycle. Without Git Hooks, maintaining consistent standards across a team can be difficult. For example, the following issues may arise: Developers may forget to run linting or tests before committing. Sensitive files like API keys or credentials might accidentally get pushed. Commit…  ( 7 min )

Your client calls asking about delayed features. Your team scrambles to explain what went wrong. Sound familiar? The solution isn't more meetings or complex reporting systems. It's a simple 5-minute daily health check that catches problems before they explode. This proven format helps agencies predict project success with remarkable accuracy.

Here's how I built the git analysis engine that powers GitNarrative's story generation. Every git repository tells a story, but extracting that story programmatically is complex. Consider these real commit messages from a typical project: "fix bug" "refactor" "update dependencies" "THIS FINALLY WORKS" "revert last commit" "actually fix the bug this time" The challenge is identifying patterns that reveal the actual development journey - the struggles, breakthroughs, and decision points that make compelling narratives.

Most of us think AI is just for generating blog posts, stock images or videos, or building websites.

Another morning, another wasted productivity hour. You know the drill - that precious time before classes when you convince yourself you'll knock out something meaningful. Instead, I stared at screens and questioned my life choices. Funny how we label days as "breaks" then fill them with work anyway. Today was supposed to be my off day - no networking, no workout, no commitments. Just rest. What did I actually do? Linear regression revision and portfolio website fixes. My portfolio site has become this ongoing project where I use AI to debug and optimize. It's not just about the final product - it's about developing this hybrid workflow where human creativity meets machine efficiency. The debugging process with AI assistance has become almost meditative. You describe the problem, the AI su…  ( 6 min )

Automating Android app documentation and testing with artificial intelligence The Initial Challenge I was facing a specific challenge: I needed to automatically document various flows of an Android application. That's when I started exploring ways to accomplish this process, and one of the tools I decided to test was Claude Code. Initially, Claude Code didn't adapt very well. However, as an Android developer, during a chat conversation, it was demonstrated how to use ADB commands to simulate user actions like clicks, typing, and other interactions, so that the AI could control my smartphone. I thought about looking for an MCP (Model Context Protocol) that already implemented this functionality, but I couldn't find any suitable one, so I decided to build my own: Android-Debug…  ( 8 min )

All good things must come to an end, including my explorations of how ngrok engineers use ngrok for play. While the rest of this series has been about homelabs, the last entry is something completely different: a serverless URL shortener that runs entirely on ngrok. No upstream services, you say? Everyone's a fan of maintaining less. -- I used to run a URL shortener in college. That was a mistake, but you know, once you start running something you can't stop running it, so I've been running it forever, ever since then. It would be nice to run it with no servers involved because maintaining servers is fun, but not maintaining them is also fun. Since I started working at ngrok, I noticed that many work-related URLs are long and hard to read, like https://www.notion.so/ngrok/$PAGE-TITLE-$sup…  ( 9 min )

This video tells the story behind Phil Collins' iconic hit, "In The Air Tonight." It reveals how the song—and that legendary drum fill that pretty much is the '80s—was born from intense personal heartbreak following the collapse of his first marriage. The piece also explores how Collins became an absolutely ubiquitous figure during the decade. He was a superstar who sold millions of records, but his omnipresence also turned him into a pop culture punchline, leading to a major backlash and, eventually, a reassessment of his work.

TLDR Setting CPU and memory requests too high in Kubernetes wastes money and reduces cluster efficiency. This guide shows you how to identify overprovisioned workloads, use Vertical Pod Autoscaler (VPA) to right-size your pods, and implement Karpenter for smarter node scaling. You'll also learn to monitor costs and validate your improvements with real metrics. When you set resource requests too conservatively in Kubernetes, your cluster reserves more capacity than workloads actually need. This leads to underutilized nodes and higher cloud bills. The problem gets worse at scale - imagine 200 pods each requesting 2 CPU cores but only using 200m. That's 400 reserved cores when actual demand is closer to 40 cores. The solution involves right-sizing both your pods and nodes. You'll use monito…  ( 11 min )

Ever wonder what became of "Bruce," the notoriously difficult mechanical shark from Jaws? While most of the animatronic is long gone, Adam Savage found an incredible surviving piece at Propstore: the original mechanical eyes! The coolest part is that this very mechanism was saved by the shark's creator, effects artist Bob Mattey. There's even an old newspaper photo showing him holding these exact eyes during the film's production. Watch on YouTube  ( 5 min )

Hi reader! We’ll begin with the complete basics and gradually build strong mental models that will give you confidence when developing your next Nest.js project. I created this series after doing a lot of research and realizing that there weren’t enough resources that go deep into the framework for people starting. Most tutorials jump straight into practical usage without first building a strong foundation for beginners. This series is the resource I wish I had when I was learning Nest.js myself. You can find the code discussed in this article HERE According to the Nest.js documentation: “Nest (NestJS) is a framework for building efficient, scalable Node.js server-side applications.” Let’s break down this simple definition to understand what it means: Nest.js as a framework: A framework…  ( 8 min )

Local large language models (LLMs) provide significant advantages for developers and organizations. Key benefits include enhanced data privacy, as sensitive information remains entirely within your own infrastructure, and offline functionality, enabling uninterrupted work even without internet access. While cloud-based LLM services are convenient, running models locally gives you full control over model behavior, performance tuning, and potential cost savings. This make them ideal for experimentation before running production workloads. The ecosystem for local LLMs has matured significantly, with several excellent options available, such as Ollama, Foundry Local, Docker Model Runner, and more. Most popular AI/Agent frameworks including LangChain and LangGraph provide integration with these…  ( 11 min )

Data States Encryption It is highly recommended to encrypt both Data at Rest and Data at Transit Symmetric Key Encryption uses same key for both Encryption and Decryption Example Encryption Algorithms DES – Data Encryption Standard Triple DES AES – Advanced Encryption Standard IDEA - International Data Encryption Algorithm Advantages Security: Algorithms like AES take billions of years to crack using brute-force attacks. Speed: Because of its shorter key it is much faster to execute and uses less resources (CPU, Memory) to Encrypt and Decrypt Industry adoption and acceptance: Algorithms like AES have become the gold standard of data encryption because of their security and speed benefits and hugely in use industry wide. RECOMMENDED for Bulk Data Transfers Challenges How to secure encryption key ? How to share encryption key ? Asymmetric Key Encryption uses two keys: Private and Public Keys Encrypts data with public key and decrypts with private key Example Encryption Algorithms RSA: Digital Signature Standard DSC: Digital Signature Standard DSA: Digital Signature Algorithm ECC: Elliptical Curve Cryptography Advantages Private key is not shared. Overall process is more secure when compared to Symmetric key encryption Disadvantages The encryption process is slow Resource utilization is very high Not recommended for bulk data transfers Cloud KMS is used to centrally manage encryption keys on GCP Supports both Symmetric and Asymmetric key encryptions Use KMS generated encryption keys in your applications and GCP Services (Compute Engine, Cloud SQL) KMS provides an API to encrypt, decrypt or sign data which can be used in our Application Development.

If you've hung around developer forums, you've probably seen this debate: Camp A: "Data structures and algorithms are academic. In real jobs, you'll never use them." Camp B: "Everything you do is built on data structures and algorithms. You just don’t realize it." It reminds me of something from school: "I'll never use math in real life." And yet, math pops up everywhere—from splitting bills to calculating interest to understanding mortgage payments. As a developer, I recently hit this same "algorithm reality check" while building SnipMaster, a text management and manipulation suite for Windows. Specifically, I'm in the process of adding live PDF editing—and discovered that the entire feature depends on Text Block Recognition, powered by a heuristic grouping algorithm. PDFs are tricky.

During the spring and summer, I've been testing different AI tools for their ability to generate accessible Android user interfaces. This post is the final testing post in the series. I will then write a recap post to summarize all my findings. The drill is the same for this test as well - I generated an Android app with Claude and then tested it with various accessibility tools, settings, and assistive technologies. Let's first talk about the app I generated. This time, too, I did only one round of tests. The reason is similar to that of the previous tests with Cursor - the setup. I didn't want to pay $20 for this one blog post, so I'm using the free version, which means I'll need to operate within Claude's app and use the chat feature.

In 1859, Charles Darwin proposed that species evolve through natural selection—small, advantageous changes accumulating over generations until entirely new forms of life emerge. Today, we're witnessing something remarkably similar, except the evolution is happening in digital form, measured in hours rather than millennia. Welcome to the age of the Darwin Machine, where artificial intelligence systems can literally rewrite their own genetic code. The distinction between traditional software and these new systems is profound. Conventional programs are like carefully crafted manuscripts—every line written by human hands, following predetermined logic. But we're now building systems that can edit their own manuscripts whilst reading them, continuously improving their capabilities in ways their…  ( 11 min )

Introduction When you bring DevOps into a company, things usually start with speed. Teams want to release faster, deploy smaller changes more often, and fix issues quickly. That part is exciting. But then comes the question nobody wants to ask in the middle of a fast release cycle: “Are we compliant?” Compliance is not just a checklist that you send to the auditors once a year. It is about proving that your systems are secure, your data is handled properly, and that your processes can align with regulatory standards, and can be trusted. The problem is, DevOps and compliance often feel like they are two sides of a coin. One side wants to get everything done ASAP. The other side wants proof for every work done. I have seen this conflict up close with engineering teams in different indust…  ( 9 min )

Ahmir "Questlove" Thompson, the legendary drummer for The Roots, is much more than a timekeeper for the band—he's a historian charting America's story through its music. His award-winning films, like Summer of Soul and the new Sly Lives!, dig into how culture and sound shape each other. A key insight comes from funk legend Sly Stone, who said social "disarray" made his job as a musician easier because it gave him something important to say. It’s a powerful reminder that we often only make sense of our chaotic times, and the art they inspire, by looking back on them years later. Watch on YouTube  ( 5 min )

In the world of web development, APIs (Application Programming Interfaces) are the bedrock of communication between different software systems. Traditionally, this communication has been a one-way street: your application "pulls" data from a server by making a request. But what if the server could "push" data to you the moment it's available? This is the powerful concept behind the Webhook API, a cornerstone of modern, real-time web applications. This guide will provide a deep dive into Webhook APIs. We'll explore what they are, how they fundamentally differ from traditional APIs, and why they are essential for building efficient, event-driven systems. We will also walk through a practical example of how to develop and test a webhook handler locally using Node.js and the open-source tool, …  ( 12 min )

In the world of software development and team collaboration, real-time notifications are not just a convenience—they're a necessity. Whether it's a notification about a new user signing up, a CI/CD pipeline completing, or a critical system alert, getting information to the right people at the right time is crucial. This is where Slack Webhooks come in, providing a powerful yet simple way to push updates from your applications directly into your Slack channels. This comprehensive guide will walk you through everything you need to know about Slack Webhooks. We'll cover what they are, how to create them, and how to send messages using them. We'll also build a practical example using Node.js and show you how to overcome the common challenge of testing webhook integrations on a local developmen…  ( 10 min )

Mastering HubSpot Webhooks: A Developer's Guide to Local Development HubSpot is a powerful CRM and marketing automation platform, but its true potential is unlocked when you start building custom integrations. Webhooks are the cornerstone of these integrations, allowing your applications to receive real-time notifications about events happening in a HubSpot account. However, developing and testing webhooks can be a frustrating experience. HubSpot needs to send data to a public, secure (HTTPS) URL, but your development environment runs on localhost, which is inaccessible from the public internet. This creates a classic development gap that can slow down your workflow with endless deployments just to test a small change. This comprehensive guide will show you how to solve this problem perm…  ( 12 min )

In the world of web development, getting real-time data is crucial for building modern, responsive applications. For years, the standard method was API polling, where your application would repeatedly ask a server, "Is there anything new yet?" This is like a child on a road trip asking "Are we there yet?" every five minutes—inefficient and resource-intensive. This is where web hooks come in, offering a more elegant, efficient, and modern solution. This comprehensive guide will demystify web hooks (often spelled as a single word, "webhooks"). We'll dive deep into what they are, how they fundamentally differ from traditional APIs, and why they've become an indispensable tool for developers. We'll go beyond theory and walk you through building a practical webhook listener using Node.js and Ex…  ( 15 min )

In the world of software development, seamless communication between different applications is crucial. For years, the primary method for this was the API (Application Programming Interface). However, a more efficient and modern approach has become standard for real-time events: the webhook. If you've ever heard the term but been unclear on the exact webhook meaning, this guide is for you. Imagine you've ordered a pizza online. You have two ways to know when it's ready. You could repeatedly call the restaurant every five minutes and ask, "Is my pizza done yet?" This is like a traditional API, where you have to constantly ask for updates. Or, the pizza shop could send you a text message the moment your pizza comes out of the oven. This is a webhook—an automated, real-time notification. This…  ( 10 min )

In the data engineering and data science space, reproducibility and environment management are just as critical as writing efficient code. Few things derail productivity faster than dependency hell when different projects require conflicting versions of Python libraries. This is where Anaconda comes in.

In crypto, "market cap" is often treated like a scoreboard. Numbers go up, headlines follow, and the industry congratulates itself. But focusing on market cap in isolation can be misleading. That’s why I found Volodymyr Nosov’s recent piece (How to Grow a Crypto Exchange’s Capitalization) worth paying attention to. Instead of the usual PR talking points, it outlined how capitalization is really built, not just measured. Beyond Volume: Trust and Regulation Nosov points out that capitalization isn’t only about trading volumes or liquidity. Those are critical, but they can’t scale without trust. Security underpins user confidence, and regulatory clarity opens the doors for institutional capital. For example, MiCA in Europe has already unlocked banking and fintech access for crypto projects - …  ( 6 min )

Context engineering is transforming how we build reliable AI systems in 2025 The famous words of President Kennedy ring differently in our AI-driven era: "Ask not what AI can do for you - ask what you can do for AI." This shift in perspective isn't just clever wordplay; it represents a fundamental transformation in how we approach artificial intelligence development in 2025. We've moved beyond the era of throwing massive datasets at models and hoping for the best. The breakthrough insight reshaping AI development today is surprisingly simple: feeding AI systems small portions of highly relevant data dramatically outperforms drowning them in trillions of lines of code. For the past decade, the AI mantra has been clear: bigger datasets, longer context windows, more parameters. But recent res…  ( 8 min )

That wild, hack-and-slash mini-game, Snake's Nightmare, is officially making a comeback in the Metal Gear Solid Δ: Snake Eater remake. The gameplay shows Snake ditching his usual stealth gear to fight off enemies with a brutal pair of hook swords. Getting to this bizarre dream sequence is an easter egg in itself. After you've endured the torture room scene at Groznyj Grad, all you have to do is save your game and then immediately reload it to be thrown into the nightmare. Watch on YouTube  ( 5 min )

Looks like the remake of Metal Gear Solid 3, now called Metal Gear Solid Delta: Snake Eater, is a hit. The review calls it a safe but successful take on the classic, basically meaning it doesn't reinvent the wheel but does a great job shining it up. This is a complete rebuild, not just a simple remaster. They've modernized the visuals, tweaked the game design, and updated the controls to make sure it plays less like a relic and more like a proper modern action game. Watch on YouTube  ( 5 min )

Here's your first extended look at the Metal Gear Solid Delta: Snake Eater remake, showing off nearly an hour of gameplay. The footage was captured on a monster PC, showcasing the game running in 4K at 60FPS with all the settings cranked to the max. True to the series, the beginning is heavy on the story and cutscenes. You'll see the Virtuous Mission setup and the iconic HALO jump, but the actual gameplay doesn't really kick in until about 16 minutes into the video. It's a gorgeous-looking slice of Snake's jungle adventure. Watch on YouTube  ( 5 min )

The remake of Metal Gear Solid: Snake Eater is a major visual glow-up that delivers a strong dose of "modernized nostalgia." The reviewer says the classic stealth-action gameplay still holds up beautifully, and the famously campy, dramatic Kojima story hits just as hard as it did on the PS2. While it's mostly a graphical overhaul without a ton of new changes, and might feel simple next to modern games, it's considered the definitive version.

it’s not every week you see an exchange CEO publish something worth bookmarking. most of the spotlight in crypto leadership still gravitates around a few loud voices - Armstrong, CZ and their likes. that’s why I found WhiteBIT CEO Volodymyr Nosov's recent piece on How to Grow a Crypto Exchange’s Capitalization refreshing. it’s practical, grounded and free from the usual PR gloss. here are the main points stood out to me: capitalization ≠ just trading volume. liquidity matters, of course, but so do security and regulatory clarity. Without trust, numbers don’t scale. ecosystem thinking. exchanges that expand beyond spot trading - into futures, staking, cards and payment rails - are the ones building long-term capitalization. smart tokenomics. utility tokens that actually integrate across products (not just sit idle on a price chart) can become a serious growth lever. what I like about perspectives like Nosov’s is that they come from building outside the biggest echo chambers. we need more of that in this industry: voices that don’t only repeat the “market cap goes brrr” mantra but actually share how to design sustainable growth. for builders and developers in Web3, that matters. because at the end of the day, the tools we create are only as strong as the trust, design, and ecosystems behind them.  ( 5 min )

Big, messy classes slow projects down and scare developers away. Every project has them. The UserManager, the DataHelper, the dreaded Utils. Classes so big and messy that nobody wants to touch them. They grow over time, swallow more responsibilities, and eventually slow the whole team down. But how do you know when a class is doing too much? Instead of guessing, you can measure it - with a metric called LCOM. LCOM stands for Lack of Cohesion of Methods. In simple terms, it measures how much the methods in a class actually belong together. If most methods use the same set of properties, the class is cohesive - that’s good. If methods work on completely different properties, the class is basically doing multiple jobs at once - that’s bad. High LCOM = low cohesion = a "god class" that tri…  ( 8 min )

1. Brute Force Try all possibilities until you find the answer. ✅ Simple but usually slow (O(2ⁿ), O(n!)). Break problem → solve subproblems → combine results. 🔑 Examples: Merge Sort, Quick Sort, Binary Search. Make the best local choice at each step → hope it leads to global optimum. 🔑 Examples: Dijkstra’s shortest path, Huffman coding. Break problem into overlapping subproblems. Save (memoize) results to avoid recomputation. 🔑 Examples: Fibonacci, Knapsack, Matrix path problems. Try a path, if it fails → go back and try another. 🔑 Examples: Sudoku solver, N-Queens, Maze solving. Work with nodes/edges (networks, maps, dependencies). 🔑 Examples: BFS, DFS, Dijkstra, Kruskal, Prim. Sorting: QuickSort, MergeSort, HeapSort, BubbleSort. Searching: Binary Search, Linear Search. A function calls itself to solve smaller versions of a problem. Often combined with DP, divide & conquer, backtracking. 🔑 Examples: GCD (Euclidean), Prime tests, Modular arithmetic. Work on text patterns and substrings. 🔑 Examples: KMP, Rabin-Karp, Trie-based search. ✅ TL;DR Optimization → Greedy or DP. Paths/Networks → Graph. Exploring possibilities → Backtracking. Ordering/Searching data → Sorting/Searching. Formula-style tricks → Math/Number theory. If you found this helpful, consider supporting my work at ☕ Buy Me a Coffee.  ( 6 min )

There are many ways to find Open Source project to contribute to, one of them is through the Open Source Software foundations. Wikipedia has a page listing all (?) the organizations.

One could go to this page, find a cause that is close to her heart and look around which organization might support that cause.

If you’ve been hanging around the dev community lately, you’ve probably noticed how often MCP (Model Context Protocol) comes up in conversations. It feels like everyone is experimenting with it whether for development workflows, database queries, or even design-to-code pipelines. I’ve been keeping an eye on MCP throughout 2024, and now that we’re well into 2025, the ecosystem has exploded with new servers and integrations. What I love about MCP is how it standardizes the way different tools APIs, databases, cloud services connect with AI agents and developer workflows. Instead of hacking together custom integrations, you can now just “plug in” an MCP server and get to work. In this roundup, I’ve pulled together some of the most practical and interesting MCP services you can use right now i…  ( 9 min )

Data analysis often involves cross-row calculations, such as Link Relative Ratio (LRR), Year-over-Year (YoY) and moving averages. Implementing cross-row calculations on ordered datasets will involve the issue of referencing adjacent members within a set.

Code in SQL: with sales as ( select column_value as amount, rownum as month from table(sys.odcinumberlist(123,345,321,345,546,542,874,234,543,983,434,897)) ), lagged_sales as ( select amount, month, lag(amount) over (order by month) as prev from sales ) select max(amount - prev) as max from lagged_sales; Window functions can reference the previous month’s sales, but…  ( 10 min )

I first heard about AI Fiesta the way most devs do—through ads promising “premium AI for pennies.” GPT-5, Claude, Gemini… all bundled into one neat package for about $12 a month.

The AI Fiesta All-Access Pass (With a Strict Data Cap) But here’s the catch they don’t lead with: the 400K token monthly cap. "Yeah, but 400,000 sounds like a lot!" you think.

Introduction: The Development Agency Scaling Problem Every dev agency dreams of scaling smoothly. But rapid growth isn't just about landing new clients or hiring more devs; scaling pains often surface as project delays, burned-out teams, and annoyed clients. Traditional project structures, with their confusing hierarchies and waterfall planning, can't keep pace in today's agile world. We asked ourselves: How could we deliver value faster, maintain code quality, and keep our developers happy? All while tackling complex, overlapping projects with shifting requirements? The answer: Rethink everything. By adopting the Spotify Model and retooling our processes (with a massive assist from platforms like Teamcamp), we saw an 89% increase in velocity without sacrificing quality or sanity.

By Frank, Senior Electronics Engineer, USA When it comes to designing printed circuit boards, the stackup - the way the different layers of copper and insulation are arranged, is crucial. Moving from a basic 2-layer board to a 4-layer design offers significant benefits in signal integrity, noise reduction, and power stability. Drawing from my years of experience, I want to share practical insights about 4-layer PCB stackups that can help you achieve reliable, high-performing designs. In simple terms, a 4-layer PCB sandwiches two signal layers on the outside with internal layers dedicated to power and ground. This arrangement helps control electromagnetic interference much better than a 2-layer board and provides solid reference planes for signals to return to, which is essential for smooth…  ( 7 min )

OK Smart Guy, Why Should I Read This? I'm going to show you a few techniques that will reduce the amount of unit tests you have to write, how you can leverage your compiler to "prove" aspects of your domain rather than wait for runtime validation, make your code easier to read and reason about, and increase refactoring safety and speed as requirements change. This is a practical guide. We're going to do our best to avoid diving into theory. ML style languages such as F# and Haskell (more commonly known as "functional programming" languages) have for many years enjoyed a set of features that makes them particularly useful for tasks such as compiler writing, automated theorem proving, and formal verification. The same qualities that make ML languages good at modeling abstract formal system…  ( 6 min )

Transaction Fee Transaction fee = Gas units * Gas price Gas units: unit of computation for executing an operation. Gas price: how much ETH you pay for every gas unit, it is composed of base fee and priority fee (tip). Gas limit: the maximum gas you allow for one transaction. Gas refund: unused gas will be refunded to sender after the transaction finish. Out of Gas: if gasUsed > gasLimit, transaction will fail and rollback all state changes, but the gas already used will not be refunded. Batching: better to split heavy computation into multiple smaller transactions to avoid exceeding gas limit. // ❌ Bad: // function doMassiveLoop() public { // for (uint i = 0; i < 1000000; i++) { // // ... do work // } // } // ✅ Good: batches uint public start = 0; uint public constant INCREMENT = 100; function doWorkInBatches() public { uint end = start + INCREMENT; for (uint i = start; i < end; i++) { // ... only do small part of work } start = end; // update next starting index }  ( 5 min )

Day 72 was a mess, but a productive one, I guess. It started with a solid night's sleep, which is rare these days. The goal is to keep my work consistent, and that's been going pretty well. Workouts, on the other hand, are another story. It's a constant battle, but I’m determined to win. I’ll be back at it tomorrow and hopefully for a few more days after that. My side project, Mutiny, is a constant presence in my thoughts. I spent a good chunk of my evening stressing over how to increase engagement on our project posts. It’s a core part of what I do, and getting people to notice it feels like the next big hurdle. Last night, I found myself in a different kind of mental gymnastics: figuring out which class I could afford to miss without my attendance dropping below the dreaded 75% mark. It's a weird kind of strategic planning that every student who's also a builder knows all too well. This morning was all about college prep. I was deep into OCaml for a quiz on Monday and exams next week. Just finished my revision of Python libraries, and tomorrow I’ll be moving on to linear and ridge regression.

" | sudo tee /var/www/html/index.html ✅ Final Result 💡 What I Learned How to connect to it securely using SSH. How to install and use a basic web server (Apache). How to serve web content on the internet using public IPs. The Challenges I faced. One of the main challenges I encountered was getting the correct command syntax while setting up the Apache web server. I kept making small mistakes — like missing sudo, using the wrong file paths, or incorrect echo/tee syntax. Every time I tried and failed, I learned a bit more about how Linux commands work. It was frustrating at times, but I didn’t give up. Instead, I double-checked documentation, retried with corrections, and gradually figured out what worked. That process — of failing, adjusting, and trying again — is called persistence, and it’s a crucial part of learning anything new in tech. When I finally saw “Hello from EC2!” in my browser, it wasn’t just a web page — it was a result of patience, problem-solving, and persistence. 📌 Next Steps Set up a domain name and connect it using Route 53.

Databases are the backbone of most applications, but as they grow, performance can take a hit. Imagine a massive User table stuffed with profile details, login history, and billing information. Queries slow down as the database scans irrelevant columns for every request. Sound familiar? Let’s explore vertical partitioning—a powerful technique to streamline your database—and touch on caching for even faster data retrieval. What Is Vertical Partitioning? Vertical partitioning splits a wide table into smaller, focused tables based on usage patterns. Instead of one bloated User table, you create separate tables for specific data groups. This reduces the number of columns scanned during queries, boosting performance and minimizing disk I/O. Profile details: name, email, profile picture As the t…  ( 6 min )

When writing Java programs, you’ll often need to choose between two values depending on whether a condition is true or false. Normally, you might use an if-else statement for this, but Java also gives us a more concise way: the conditional operator, also known as the ternary operator (?:). The General Form: condition ? valueIfTrue : valueIfFalse Java checks the condition, which must evaluate to either true or false. If the condition is true, the whole expression evaluates to valueIfTrue. If the condition is false, the whole expression evaluates to valueIfFalse. This allows you to write decisions in a single line of code. int x = 5, y = 10; int min = (x < y) ? x : y; System.out.println(min); This evaluates to the same result as writing; int min; if (x < y) { min = x; } else { min = y; } Final Thoughts The conditional operator is a handy shortcut that can make your Java code more elegant. For quick decisions between two values, it’s often better than writing out a full if-else block. Next time you need to choose between two options, try using ?: and see how much cleaner your code looks!  ( 6 min )

Preface In Solidity, there are two kinds of arrays: Fixed-size array: You must specify array length at declaration time. Example: uint[5] numbers; Once created, the length is not possible to change. Dynamic-size array: No need to specify length at declaration. Example: uint[] numbers; The length can be changed at runtime (grow or shrink). Most common syntax uint[5] numbers; // fixed size array uint[] numbers; // dynamic array numbers[i]; // access by index uint[] storage refToNumbers = numbers; // storage reference function f(uint[] memory a) external { ... } // pass memory array numbers.push(x); // append to end numbers.pop(); // remove the last element uint n = numbers.length; // get length delete numbers[i]; // reset value to default for (uint i = 0; i < numbers.length; i++) { ... } // loop When declaring an array inside a function, you must use the memory keyword. A memory array always have fixed size, so you cannot call push or pop. You can use the new keyword to create a memory array based on a variable size. Example: function createMemoryArray(uint size) public pure returns (uint[] memory) { uint[] memory newArr = new uint[](size); return newArr; }  ( 5 min )

Você já percebeu que algumas funções “lembram” valores mesmo depois que o componente re-renderiza? Isso acontece por causa de closures. Em JavaScript, uma closure é quando uma função consegue acessar variáveis do escopo onde foi criada, mesmo depois desse escopo ter sido executado. Exemplo simples em JS puro: function contador() { let count = 0; return function() { count++; return count; }; } const incrementar = contador(); console.log(incrementar()); // 1 console.log(incrementar()); // 2 console.log(incrementar()); // 3 A função incrementar mantém acesso à variável count, mesmo depois que contador() já terminou de executar. Isso é uma closure em ação. O problema no React Ao digitar num input e disparar uma busca a cada tecla, sua API sofre. Queremos esperar o usuário parar…  ( 6 min )

Implementing push notifications on Android or iOS is rarely straightforward. On iOS, you’ve got APN certificates to generate and renew. On Android, you’re dealing with Firebase server keys. And then there’s the fun part figuring out why your notification never arrived, even though nothing looks obviously broken. These failures are often silent, and the logging you get isn’t always helpful. Most apps rely on push notifications for engagement: reminders, updates, alerts. But the tooling around them? Honestly, it’s more complex than it needs to be. Between platform differences, cryptic error messages, and all the moving parts in the setup, it becomes a pretty heavy lift for mobile developers. This is where Clix.so, a notification platform built for developers, plays the part. This platform r…  ( 10 min )

When developing your frontend application, most of the time you work with the data coming from or sending it somewhere. And as discussed in this five-layer MVVM implementation, you have to use the repository for these purposes. It sits just above the network or browser APIs, providing a clean, testable interface to the rest of your app. TIP: If you haven’t read my MVVM Introduction yet, I highly recommend doing that first. It’ll help you understand where the data layer fits in the bigger picture. In this article, you’ll learn: What a repository is and when to use it. Practical implementation with the source code.

Thats right, prediction are not the same as calculations, and LLMs don't calculate, they predict the next word. Stanford's HELM report shows GPT-4 hits 90%+ accuracy on math tasks.

What is AGENTS.md and Why Should You Care? Vladislav Guzey ・ Aug 21 #ai #programming #tooling #productivity  ( 5 min )

If you’re like me and work with multiple AI coding agents, you know the frustration of managing different instruction files. It’s a pain to keep everything updated across various formats. But I’ve got some great news for you. A new, simplified standard has emerged, and it’s called AGENTS.md. For a while now, working with different AI agents meant juggling multiple configuration files. Whether it was claude.md, gemini.md, or .cursor/rules, each agent had its own format. This created a mess of redundant files that all needed to be updated separately. It was inefficient and confusing. Big companies recognized this problem. They came together to create a unified solution — AGENTS.md. The goal was to establish a single, predictable place for all AI agents to find the instructions they need to …  ( 7 min )

When web projects outgrow the comfort zone of a single server, developers often face a familiar chain of problems: downtime during deployment, inconsistent environments, unpredictable traffic spikes, and complex scaling decisions. Traditionally, teams relied on manual server configurations or fragile scripts to keep applications alive. In a classic setup, hosting an application meant provisioning a server (or a VM), installing dependencies, and hoping that the CPU and memory would hold up under load. Scaling usually meant either moving to a larger server (vertical scaling) or setting up additional ones (horizontal scaling), often managed by hand. Kubernetes to the Rescue Kubernetes (K8s) is an open-source architecture system designed exactly for these pain points. Instead of treating serve…  ( 7 min )

In my previous blog, we explored how to verify file integrity during transfers using SHA-256 checksums. So how do we make it tamper-proof and also be able to verify authenticity without jumping to heavy public key cryptography? HMAC stands for Hash-based Message Authentication Code. You take your file (or message), Combine it with a secret key that is known only to sender and receiver Run it through a hashing algorithm like SHA-256. The result is a hash that can only be reproduced if you have both the exact file and the shared secret key. Why this matters: Generate HMAC-SHA256 hash of the file using the shared secret key. Send both the file and the generated HMAC hash. Recompute HMAC-SHA256 hash of the received file using the same key. Compare it with the sent hash. Match ✅ → file is intac…  ( 7 min )

One of the most powerful exercises in the ALX Software Engineering Program is creating a vision board — a snapshot of who we want to become in the near future. When I look at my vision board, I see more than just pictures. I see a commitment: A laptop filled with code reminds me that I will grow into a confident front-end developer. A smiling remote worker represents the balance I aim to achieve — building a career while maintaining personal well-being. A group of people symbolizes collaboration with my peers, because growth at ALX is never just personal, it’s shared. A certificate stands for recognition, celebrating the wins both big and small. The beach scene shows my dream of flexibility — working from anywhere in the world. And finally, the growth icons remind me to keep learning, keep evolving, and keep contributing. This vision board is not only about where I want to be in 4 months, but also who I am becoming every day. With the support of ALX and my peers, I know this journey will be both challenging and rewarding.  ( 5 min )

The Waterfall Model in software engineering is one of the earliest approaches to software development. It follows a strict linear sequence where each stage must be completed before moving to the next. While it is simple and well-structured, it also has several limitations that modern methodologies attempt to solve. The Waterfall Model is a sequential software development process. It was first introduced in 1970 by Dr. Winston Royce. The model is called "waterfall" because progress flows in one direction, similar to a waterfall, without going back to previous phases. The development life cycle under this model usually includes: Requirement Analysis – Collecting and documenting all project requirements. System Design – Creating architecture and design based on requirements. Implementation (C…  ( 6 min )

Learning a new skill is never easy; and programming has proven to be one of the hardest challenges I’ve faced. I began my coding journey in 2024 when I joined ALX, knowing nothing but eager to write those magical lines of code that bring apps or games to life. But reality hit me very fast. We began with Shell basics, which were smooth, then moved to C language, which humbled me. Starting C, I thought: “If I can print Hello, World!, then I can do anything.” On came about functions, pointers and arrays which didn’t just confuse me but crush me to the pits. Instead of truly learning, I took shortcuts: copying code just to pass. Soon, I was drowning in recursion, data structures, and memory allocation without understanding the foundations. By June 2024, I knew I had to take a step back: I felt guilty, defeated, and convinced maybe programming wasn’t for me. Still, the dream never left. After months of reflection, I realized the first thing I needed to fix wasn’t my code; it was my mindset. Now, as I restart my journey, I come better prepared: mentally, emotionally, and practically. I know there will be long nights of debugging. I know errors will test my patience. But I also know this: quitting isn’t an option anymore. This time, my path is clear: Progress >>> Perfection.  ( 5 min )

When most people imagine Data Science, they picture building shiny machine learning models or crafting beautiful dashboards. if your data is messy, no model can save you. That’s why people say: “80% of a data scientist’s time is spent cleaning data.” And it’s not a joke. Missing values → blank cells, NaNs, or inconsistent entries. Duplicates → one user recorded multiple times. Outliers → extreme values like a salary of $1,000,000,000. Inconsistent categories → Nairobi, NBO, 254-Nairobi treated as different. Wrong data types → numbers stored as text. Here’s how I usually tackle some of these: import pandas as pd # Example dataset data = { "Name": ["Alice", "Bob", "Charlie", "Alice"], "Age": [25, None, 37, 25], "Salary": [50000, 60000, 1000000000, 50000], # notice the outlier "City": ["Nairobi", "NBI", "254-Nairobi", "Nairobi"] } df = pd.DataFrame(data) print("Before Cleaning:") print(df) # 1. Handle missing values df["Age"].fillna(df["Age"].median(), inplace=True) # 2. Drop duplicates df.drop_duplicates(inplace=True) # 3. Fix inconsistent categories df["City"] = df["City"].replace({"NBI": "Nairobi", "254-Nairobi": "Nairobi"}) # 4. Handle outliers (example: cap salaries above 200k) df["Salary"] = df["Salary"].apply(lambda x: min(x, 200000)) print("\nAfter Cleaning:") print(df) Before Cleaning: Name Age Salary City 0 Alice 25.0 50000 Nairobi 1 Bob NaN 60000 NBI 2 Charlie 37.0 1000000000 254-Nairobi 3 Alice 25.0 50000 Nairobi After Cleaning: Name Age Salary City 0 Alice 25.0 50000 Nairobi 1 Bob 25.0 60000 Nairobi 2 Charlie 37.0 200000 Nairobi Don’t ignore missing values, understand the why before filling/dropping. Standardize categories early to avoid “ghost” groups. Outliers may be errors or real rare events, investigate before deleting. A clean dataset can outperform a complex model trained on dirty data.  ( 6 min )

Early-stage startup founders live in constant motion such as pitching investors, refining products, and fighting for traction. In this hustle, customer relationships often take a back seat. Yet ignoring them early can be one of the costliest mistakes. Three reasons stand out: Acquisition costs are rising. Customer acquisition cost (CAC) for SaaS has jumped more than 60% in five years, making paid ads unsustainable. Investors expect clarity. By Seed or Series A, you need metrics like CAC, LTV, churn, and funnel conversion. Without a system in place, these numbers are messy or missing. That is why customer relationship management (CRM) must be seen not as software you buy later, but as the foundation of growth. Whether you’re in SaaS, FinTech, HealthTech, or Energy, CRM ensures every lead is…  ( 8 min )

ℹ️ Re-posted from stripe.dev While working remotely and traveling from place to place, I noticed a recurring pattern. Every time you arrive in a new city, you rent an Airbnb or check-in to a hotel. Then you sign up for a gym and a co-working space. Payments for these services are all done electronically. But when it comes to access, you need a plastic card, a fob, or a physical key. This creates friction for everyone involved. You have to go pick it up, carry it around, hope you don’t lose it, and return it before leaving. From the business side, they need to pay someone to work the front desk to issue, track, and collect these access devices. This made me wonder, what if access was fully digital? Luckily, there is a better way that is gaining popularity. Instead of cards and keys, w…  ( 9 min )

The Enigmatic 'this' Keyword in JavaScript JavaScript's 'this' keyword is a source of confusion for many developers, but unraveling its mysteries can lead to a deeper understanding of the language's inner workings. Global Scope When used in the global scope, 'this' refers to the global object, which in a browser is the window object. console.log(this === window); // true Object Methods Within an object method, 'this' refers to the object itself. const person = { name: 'John', greet() { return Hello, ${this.name}!; } }; console.log(person.greet()); // Hello, John! Constructors When used in a constructor function, 'this' refers to the instance being created. function Car(make) { this.make = make; } const myCar = new Car('Toyota'); console.log(myCar.make); // Toyota Event Handlers In event handlers, 'this' typically refers to the element that triggered the event. document.querySelector('button').addEventListener('click', function() { console.log(this.textContent); }); By understanding the various contexts in which 'this' is used, developers can harness its power to write more effective and efficient JavaScript code.  ( 5 min )

Intro In one of my previous posts, I wrote about features between Java LTS versions 21 and 17. Now, two years later (how!? Two years already!?), a new LTS version is scheduled for release on September 16, 2025 — Java 25. Today, it has moved into the "Final Release Candidate" phase, and the feature set is frozen.

If you've ever pushed a change to production and your browser stubbornly kept showing you the old version, you've experienced caching, probably not in a good way. HTTP caching is one of those topics that can seem deceptively simple ("it just stores stuff locally"), but the details matter. Done right, it makes sites feel lightning-fast and reduces server load. Done wrong, it causes confusing bugs and outdated resources to linger. This isn't a deep dive into every caching strategy, it's the quick, developer-focused overview I wish I had when I first started building for the web. At the end, you'll find resources for going deeper. Fetching resources over the network is slow and expensive, not just in terms of latency, but also in wasted bandwidth and server strain. Caching lets us store a…  ( 11 min )

I’ll be honest. Few things are more frustrating than solving a problem by reaching for a great package… only to realize the problem is still there. That was me last week, yelling at my API like it had just spoiled the finale of a Netflix show. I was using Spatie’s Laravel ResponseCache package. It’s rock solid, it works out of the box, and it’s built by people I trust. But here’s the kicker: I turned it on in production and suddenly my multilingual API was speaking one language only. The first request cached in English. Every Arabic request after that? Still English. So here’s what it took to fix it. I hope it will help some lost soul on the internet one day.

As developers, we spend weeks (sometimes months) training, fine-tuning, and deploying AI models. But here’s the uncomfortable truth: Once they’re live… do we really own them? On most platforms, your AI ends up locked inside someone else’s infrastructure: Behind APIs, you don’t fully control Running on servers you don’t own Generating value that mostly flows back to the platform, not you That doesn’t feel like ownership. At haveto.com, we think your AI should be more than just code. Here’s how it works when you deploy AI directly on-chain with us: ✅ Your AI gets its own wallet → it earns every time it completes a task. ✅ On-chain identity → proof of ownership is transparent, forever. ✅ Portability → sell, lease, or license your AI like a real IP. This isn’t “another hosting service.” Deploy AI on-chain, earn directly from users, no middlemen. True IP protection — no one can copy-paste your model into their cloud. Cost efficiency — gas fees drop as usage grows (a real economy of scale). You’re not just pushing code anymore — you’re creating revenue-generating IP. AI runs directly on the blockchain (no third-party servers). Transparent + verifiable outputs (great for finance, healthcare, and other trust-heavy domains). Secure, scalable, and designed for real workloads. 1️⃣ Build your AI model in any language (Python, JS, Rust, we don’t force you into one). 💭 Question for the dev.to community: 👇 Let’s discuss. 🔗 haveto.com  ( 6 min )

When it comes to cloud migration, businesses are faced with a big decision: how to move their IT infrastructure and applications to the cloud. A cloud migration strategy allows companies to take advantage of flexibility, scalability, and cost savings.

When I first started attending conferences, I diligently tried to write down notes and publish them. It forced me to actively listen to the talks I was attending. With the number of conferences rising, I couldn't keep the rhythm. When I switched my career path to Developer Advocate, I drastically diminished the number of talks I attended in favor of the hallway track. As a result, the last conference "report" I wrote was JPrime's in 2022. This week, I was privileged to speak at DevOps Days Kansas City. The event was co-located with and part of KCDC. It was my first edition for both. As I'm returning to engineering, the number of conferences I'll attend in the near future will probably be very low, if not zero.

I didn’t put this article at the start of your journey - in my opinion, it’s hard to choose where you’re going if you haven’t yet seen what the road looks like, what challenges lie ahead, or who you’ll be walking beside. Now that you’ve already explored some of the core ideas of cybersecurity ( threats, frameworks, ethics, risk) - it’s the perfect moment to step back and ask: What kind of security professional do I want to become? When most people hear the word "cybersecurity", they picture someone in a hoodie hammering away at a keyboard in a dark room. In reality, though, cybersecurity is much more than just hacking or stopping hackers. It’s a vast and constantly evolving field, made up of many disciplines - each with its own tools, challenges, and mindset. Think of it like a city - the…  ( 12 min )

Hi there 👋, I have just started a mentorship journey with my manager to enhance and level up my backend and system design skills. The first challenge on my plate: Uber Now, I'm actually not building the next Uber😅 but I’ll be breaking down how such a huge system works and how to make it scalable, reliable, and fun to learn from The Game Plan (REC 🎯) My mentor gave me a simple framework to guide my thinking: R = Requirements → What exactly should Uber do? E = Environment → Who’s using it, where, and under what conditions? C = Constraints → What limits (time, money, resources, etc.) affect the design? This little formula (REC) will help me avoid running wild with random ideas and instead focus on real engineering decisions. What I’ll Be Doing Over the next two weeks, I’ll: Break down Uber’s requirements, environment, and constraints. Sketch out an architecture design. Share updates through blog posts like this.

Developers love the rush of getting something working fast. A quick proof-of-concept, a few shortcuts, and suddenly you have something that looks ready. But moving vibe-coded prototypes straight into production is one of the fastest ways to sink a project. In the short term, it feels like you are saving time. In reality, you are borrowing from the future, and the interest rate on technical debt is brutal. Vibe coding is all about momentum. You write code quickly, often with AI-assisted tools or borrowed snippets, focusing on functionality over structure. It is perfect for early experiments, demos, and validating ideas. The problem is that vibe-coded systems are rarely built for: High concurrency Maintainability by a growing dev team Regulatory compliance Reliable performance under load …  ( 6 min )

Amortisation Explained Simply: How Your Loan Payments Are Split Between Interest and Principal When you take out a loan—whether it’s a mortgage, car loan, or personal loan—you’ll often hear the term “amortisation.” At first, it might sound like complicated financial jargon. But the idea is actually quite simple: amortisation is just the process of spreading out your loan repayments over time. Understanding amortisation is crucial because it shows you exactly how much of your monthly payment goes toward interest (the bank’s charge for lending you money) and how much reduces your principal (the actual amount you borrowed). Let’s break it down step by step. Principal: The original amount you borrow (say, \$200,000 for a home loan). Interest: The cost of borrowing, usually expressed as an a…  ( 6 min )

After my 4th semester, reality hit me like a truck: “oh crap, I need to get an internship.” I applied everywhere, gave interviews, fumbled half of them, got disappointed… and finally landed an offer. Which I refused. Out of pure confusion. Then, like the clown I was, I called them back, apologized, and somehow still got the internship. At first, I was excited. Corporate life looked shiny and glamorous in my head. I chose the Full Stack department, pumped to finally do “real dev work.” …And then reality smacked me again. The work? Mundane, boring tasks. The devs? Sitting at their desks from morning to evening like NPCs on repeat. Watching them, I thought: “Wait… is this going to be my whole life??” That’s when the depression arc kicked in.

When was the last time you downloaded an app and deleted it within minutes because it crashed, froze, or simply didn’t feel reliable? You’re not alone-according to a 2023 TechRadar survey, 70% of users uninstall an app within a week if they encounter performance issues. That’s the brutal reality of the digital world: users have zero patience for buggy apps. This is exactly where mobile app test automation comes in. I still remember working on my first mobile project as a junior tester. It was a simple e-commerce app, and everything looked fine during manual testing. But once the app hit the real world—with hundreds of devices, OS versions, and unpredictable user behaviors-it fell apart. Cart errors, login glitches, and payment bugs all showed up within days. It was painful. That was my wak…  ( 8 min )

Inspired by @ihssmaheel and his guide to Rust for JavaScript developers I decided to start learning this general-purpose programming language from scratch. Of course, I do know other languages, but JavaScript is the one I’m using every day at work for years. I’ll share my progress with you in this beginners-oriented series. Before proceeding, here’s what I’m going to do: I plan to follow The Rust Programming Language, but in its forked version published by the Brown University. I chose to do so, because this one is more interactive than the original version, and I think it would be better for me. It’s also recommended by the language maintainers.

If you’re building a new product, website, or app, choosing the right content management approach can save you a lot of time and scaling issues later. Traditional CMS platforms like WordPress work well initially but can limit flexibility as your needs grow. This is where Headless CMS comes in. What is a Headless CMS? A Headless CMS is a content management system where the backend (content storage) is separated from the frontend (your website or app). Instead of using built-in themes, you connect your CMS to frameworks like Next.js, React, or Vue.js via APIs. Benefits for Startups & Developers Flexibility: Design your frontend exactly how you want without CMS restrictions. Scalability: Your content can be reused across websites, apps, and other platforms. Faster Development: Developers can use modern frameworks and workflows. Future-Proof: Since the frontend and backend are decoupled, you can upgrade or replace one without breaking the other. Popular Headless CMS Options Here are some beginner-friendly and powerful Headless CMS platforms to explore: Sanity.io – Great for real-time collaboration and flexible APIs. Builder.io – Visual editor combined with headless CMS features. Contentful – A popular enterprise-ready CMS. When to Use Headless CMS? If your project needs custom frontend, supports multiple platforms (web + mobile), or requires high scalability, then headless CMS is a strong choice. Startups benefit because it avoids lock-in and allows teams to grow their tech stack over time. Pro Tip Pair your Headless CMS with frameworks like Next.js or Nuxt.js for smooth rendering and SEO-friendly performance. Note: If you’re a startup or developer exploring headless CMS solutions, working with an experienced web development company can make the integration process much easier. Companies like RW Infotech specialize in modern development stacks and headless CMS implementation. https://www.rwit.io/service/web-development  ( 6 min )

SurrealDB: shiny newcomer, low-level database, or both? SurrealDB is admittedly a pretty shiny database. It's built in Rust, a programming language that has just barely hit the 10-year mark since it hit version 1.0. A good deal of attention is paid to the website and brand design, and the official Surrealist app is not only slick but even capable of visualizing data as an interconnected net of records. This blog post goes into further detail on how this graph visualization works, leading to output like the following that lets you see which European countries belong to which intranational groups. But the other side of being a database written in a low-level language like Rust is that you can compile it to machine code with a single command and do everything you want with it on the comman…  ( 21 min )

🚀 My Journey with SQL on Oracle LiveSQL | Assignment Practice As part of my DBMS assignment, I decided to go hands-on with Oracle LiveSQL and practice real-world SQL queries. What started as just another task turned into an exciting journey of creating tables, inserting data, altering structures, and running some powerful queries. Let me walk you through my experience! 🏗 Step 1: Creating Tables I began with three main tables: Students – to store student details Courses – to hold course information Enrollments – to manage the many-to-many relationship between students and courses CREATE TABLE Students ( CREATE TABLE Courses ( CREATE TABLE Enrollments ( 📸 Screenshot proof of successful table creation: ✍️ Step 2: Altering & Inserting Data Next, I added a Phone Number column to the Students table and inserted some sample data. ALTER TABLE Students ADD (PhoneNo VARCHAR2(10)); INSERT INTO Students (StudentID, Name, Dept, DOB, Email) VALUES alice@example.com'), bob@example.com'), charlie@example.com'); 📸 Screenshot proof of inserted rows: I queried all student names in uppercase and calculated the length of their email IDs: SELECT UPPER(Name) AS StudentName, LENGTH(Email) AS EmailLength ✅ Output: STUDENTNAME EMAILLENGTH 📸 Screenshot of results: I also tried aggregate functions to calculate the average credits of courses and the total number of students: SELECT AVG(Credits) AS AvgCredits, COUNT(*) AS TotalStudents 📸 Screenshot output: 💡 Key Takeaways SQL is more powerful than it looks – even small queries give deep insights. Working with constraints (PRIMARY KEY, FOREIGN KEY, UNIQUE, CHECK) is essential for maintaining data integrity. Oracle LiveSQL is a fantastic tool for learning + testing SQL without needing local installation. 🎯 What’s Next? This was just the beginning! My next steps will include: JOIN queries to link Students and Courses. GROUP BY with HAVING for department-wise insights. Views & Stored Procedures to wrap logic neatly.

What is Pub/Sub? Publish/Subscribe (pub/sub) is a messaging pattern where publishers send messages without knowing who will consume them, and subscribers receive messages without knowing who produced them. A broker (like Kafka, RabbitMQ, SQS, Redis) usually sits in the middle to handle message delivery. This decoupling allows systems to communicate asynchronously and scale independently. Pub/Sub solves several common problems in distributed systems: Decoupling – Publishers don’t need to know subscribers. Scalability – Multiple subscribers can process messages independently. Reliability – Messages are queued until consumed (depending on broker). Flexibility – One message can be delivered to many subscribers (fanout). When Pub/Sub?

Your Solution 1 (Dynamic Stylesheet Injection) is excellent and definitely enterprise-grade! Here’s why it’s a strong approach, along with some enhancements to make it even more robust: Strengths: No DOM manipulation - Doesn’t touch existing elements Automatic application - CSS engine handles lazy-loaded elements automatically Performance efficient - Single style injection vs multiple DOM queries Clean rollback - Simple removal of style tag reverts everything Maintainable - All styling logic in one place Browser-optimized - Leverages native CSS cascade Here’s an improved version with better practices: clientModelHelpers.handleIdVerificationValues = function(attributes) { var context = this; var client = context.client; var field = Object.keys(attributes)[0]; if (field !…  ( 7 min )

Why This Post? When I first built my Bitcoin CLI wallet in Rust, it worked — but it was stuck in the past. 1...), which meant: Higher fees 💸 Slower confirmations 🐢 No Lightning Network ⚡ support Then I integrated SegWit (Segregated Witness), and everything changed: 35% cheaper, more secure, and finally ready for the Lightning era. In this post, I’ll break down: What SegWit really does (without the fluff) How I implemented it in Rust step-by-step Real-world results (performance, fees, and UX) What this unlocks next (Lightning, Taproot, and beyond) If you’re building wallets, apps, or just curious about Bitcoin internals, this is your practical roadmap to SegWit. SegWit is a Bitcoin upgrade (2017) that separates witness data (signatures) from the main transaction. Why it matters: Fixes t…  ( 6 min )

But here’s the reality: as business ecosystems become more real-time and API-driven, EDI on its own often struggles to keep up. Why Traditional EDI Falls Short While EDI is reliable, it wasn’t built for the modern pace of business. Companies often face: Integration delays — onboarding new trading partners can take weeks. High costs — managing legacy VANs and middleware eats into budgets. Lack of real-time visibility — data often lags, leading to shipment errors or delayed payments. According to Gartner, 60% of organizations still rely on legacy EDI systems, but more than half plan to modernize their B2B integration stack within the next 3 years. APIs as the Next Step APIs don’t replace EDI entirely—but they enhance it. Modern B2B networks now combine EDI’s structure with API’s speed and flexibility. This hybrid approach ensures compliance while enabling real-time data exchange. Benefits include: Faster onboarding of trading partners. Instant updates on order statuses and shipments. Lower integration maintenance costs. The Rise of Cloud-Native EDI Platforms Instead of building and maintaining complex EDI infrastructure in-house, companies are turning to cloud-native EDI solutions. These platforms provide: Plug-and-play integrations. Automated validation of EDI messages. Real-time monitoring and error handling. This shift allows IT teams to focus less on firefighting and more on strategic initiatives. Platforms like ORDERFUL are helping businesses make this transition with flexible, API-first EDI solutions. Final Thought EDI isn’t dead—it’s evolving. The future of B2B integration lies in hybrid ecosystems where APIs and EDI coexist seamlessly. Companies that adapt now will be positioned to thrive in an increasingly digital supply chain.  ( 6 min )

Structuring an Angular app may seem straightforward at first-just put components in one folder, services in another, and models in their own. But as projects grow, that neat separation can quickly turn into a maze of files. Reflecting on a recent project, I realized how much time I wasted bouncing between folders just to make a small change in one feature. That’s when I decided to shift from the type-based structure to a feature-based design-and it completely changed how I build and maintain Angular apps. In this post, I’ll walk you through why this shift clicked for me, the challenges it solved, and how it makes apps more modular and scalable. 🛠️ Challenges with Type-Based Structure /components /services /models But real-world development quickly exposed its flaws: Scattered Logic…  ( 6 min )

It was 3 AM when Jake's phone buzzed. The client payment system was down, and the only developer who understood the custom API integration had left the company two weeks ago. No documentation. No comments. Just 47 files of unorganized code and a growing pile of frustrated customer support tickets. Does it sound familiar? If you are running a growing dev agency, you have lived through this nightmare. Perhaps you're a senior developer fielding endless "quick questions" at all hours.

One of the biggest myths about learning is that you need endless hours to master new skills. I’ve read over 1,500 books in the last 15 years, but nothing has accelerated my learning like using AI as a personal learning assistant. Here’s my system. 1️⃣ Summarise Smarter, Not Harder Instead of slogging through 300 pages, I use ChatGPT to: Summarise key chapters Highlight arguments and counterarguments Create mind maps 💡 Prompt: “Summarise [article/book/paper] into 5 bullet points, 2 examples, and 1 key action takeaway.” 2️⃣ Turn Notes Into Action Most people stop at highlights. I turn notes into checklists and exercises with AI. 💡 Prompt: “From these notes, create a 7-day action plan to apply the concepts in real life.” This way, learning becomes practice — not just theory. 3️⃣ Debate With AI When I don’t fully understand a topic, I argue with ChatGPT. “Act as a skeptic. Challenge my understanding of [topic] with 5 tough questions. Then help me refine my answers.” This forces deeper clarity and confidence. 4️⃣ Create Learning Systems I build structured learning plans with AI, like: Weekly reflection exercises Project-based challenges 📂 Resource: On the ReThynk AI YouTube Channel, I share live tutorials on how to design these AI-powered learning systems. 5️⃣ Teach Back What I Learn The fastest way to know if you’ve learned something? Teach it. 💡 Prompt: “Pretend you’re a 15-year-old beginner. Ask me 5 questions about [topic], and help me refine my explanations if they’re unclear.” Tools I Use Alongside AI Notion + AI → Smart knowledge management Readwise → Sync highlights from books/articles ChatGPT → Tutor, coach, and challenger ReThynk AI Templates & Frameworks → My pre-designed learning structures ReThynk AI Magazine → Curated AI & business insights (currently free on our website) Final Thought In a noisy world, the advantage doesn’t go to those who consume more — it goes to those who learn faster and apply smarter. 📌 Next Post: “5 Mistakes People Make with ChatGPT Prompts” — and how to avoid them.  ( 7 min )

Curiosity about real-world cyberattacks-like how huge botnets for DDoS attacks form-pushed me beyond the classroom. The only way to really learn was to spin up my own honeypot and watch the attackers come at me. To reach my goal, I started out with Cowrie, then later moved on to Dionaea and integrated everything with Splunk + Tailscale. The first priority was security, so I moved the SSH port into the 53,000 range and set up Tailscale VPN to give my laptop a stable IP and restrict access. I began with small Cowrie experiments, which went surprisingly smoothly aside from some networking and config hiccups. That success gave me the confidence to step up to Dionaea — a bigger challenge. Permissions became less of a roadblock thanks to what I’d learned with Cowrie, but getting Dionaea to log …  ( 6 min )
